[RESOLVED] Dispatch and Listen for a Global Event

[badaboom55]

Yes, you're right. I apologize for not trying to compile it before posting.

Meh, no problem, that's what the Compiler Panel is for! The tricky part is when nothing works and you DON'T get errors =)

I was just posting for completeness for future viewers.

Oops... not done yet apparently...

Now I'm encountering an interesting problem when I try to remove the listeners.

In ClassA (the dispatcher) I have:

Broadcaster.broadcastEvent("someEvent");

This line within ClassA is associated with an interval, so it basically tells the Broadcaster class to broadcast a "someEvent" event once a second.

In ClassB (the listening class) I have:

// in ClassB constructor
Broadcaster.addBroadcastListener("someEvent", onSomeEvent, false, 0, true);

// ClassB methods
private function onSomeEvent(e:Event):void{
    trace("Broadcast Received");
}

This all works great. I get "Broadcast Received" traced to output panel about once a second.
However, now I'm concerned with what happens when I want to destroy a ClassB instance and (hopefully) flag it for garbage collection. So, each instance of ClassB has a kill() method (called when it is removed from stage via removeChild) designed to remove "standard" listeners, children and other sub-processes to make sure that there aren't any extraneous references.
Now, I have removed the ClassB instance from the Display List, and set all external/parent references to the ClassB instance to "null"; however, I'm still getting "Broadcast Received" traced to the output panel... even though ClassB instance that has the trace() script in it has been "destroyed".
I thought that would easily be solved by removing the broadcast listener:

public function kill():void{
    Broadcaster.removeEventListener("someEvent", onSomeEvent, false);
}

I got a strange compile-time error:

1061: Call to a possibly undefined method removeEventListener through a reference with static type Class.

This threw me for a loop because Broadcaster extends EventDispatcher, so shouldn't it inherit the removeEventListener() method? Is there some reason I would need to override the EventDispatcher method?

Or, do I need to create a special removeBroadcastListener() method in Broadcaster in order to remove any listeners added? If so, what would that look like??

Thanks!
